[tex]\frac{4}{x} =12[/tex]
[tex]4 = 12x[/tex]
[tex]x= \frac{4}{12} = \frac{1}{3}[/tex]
Four divided by 1/3 equals 12.
use substitution to solve this. substitute for x, not y

A coin collection contains d dimes and q quarters worth a total of $50.
Which equation models this information?
d + q = 50
10d + 25q = 50
0.1d + 0.25q = 50
0.01d + 0.25q = 50
Answer:
0.1d + 0.25q = 50
Step-by-step explanation:
dimes are worth 10 cents so it's 0.1 and d represents the unknown amount
quarters are worth 25 cents so it's 0.25 and q represents the unknown amount

How do I simplify this complex rational expression?
Answer:
[tex]\frac{23x+3}{20(x+1)}[/tex]
Step-by-step explanation:
Separate the fractions into a more readable format.
Factorise the denominators of all the fractions where possible. For [tex]x^2-1[/tex] apply DOTS ==> Difference of two squares*
Simplify the fractions.
I wrote out my working so I hope that helps :>>
*Difference of two squares is a method of factorising the sum of two squares, where one of them is negative. [tex]a^2-b^2 = (a-b)(a+b)[/tex]
the path of a toy rocket is modelled by the equation y=-x^2+6x+2, where x is the horizontal distance, in metres, travelled and y is the height, in metres, of the toy rocket above the ground. what is the maximum height of the toy rocket? at what horizontal distance does the maximum height occur?
Answer:
The path of a toy rocket is defined by the relation y=-3x^2+11x+4, where x is the horizontal distance, in meters, traveled and y is the height, in metres, above the ground.
Determine the zeros of the relation.
-3x^2 + 11x + 4 = 0
---
3x^2 - 11x -4 = 0
Factor:
3x^2 - 12x + x - 4 = 0
---
3x(x-4) + x-4 = 0
---
(x-4)(3x+1) = 0
---
x = 4 or x = -1/3
============================
f(x) = -3x^2+11x+4
How far has the rocket traveled horizontally when it lands on the ground?
4 ft.
==================
What is the maximum height of the rocket above the ground, to the nearest hundredth of a meter?
---
max occurs when x = -b/2a = -11/(2*-3) = 11/6
height = f(11/6) = 14.083 ft

5x +2y=-9
3x+4y= -11
por el método de igualacion porfavor hacerlo en folio y me mandáis una foto si no no entiendo
Answer:
x = -1
y = -2
Step-by-step explanation:
5x + 2y = -9 2y = -9 - 5x y=(-9-5x)/2
3x + 4y = -11
3x+4[(-9-5x)/2] = -11
3x+( -36-20x)/2 = -11
3x-18-10x = -11
-7x = 7
x = -1
y = -2
Answer:
x = −1 and y = −2

In a basketball game Elena scored twice as many points as Tyler Tyler scores four points fewer than Noah and Noah scores three points as Mai of Mai scores 5 points how many points did Elena score
Full question:
In a basketball game, Elena scores twice as many points as Tyler. Tyler scores four points fewer than Noah, and Noah scores three times as many points as Mai. If Mai scores 5 points, how many points did Elena score? Explain your reasoning
Answer and explanation:
We start from known to unknown. We know that Mai scored 5 points and so we work from here.
Since Mai scored 5 points and Noah scored three times as many points then Noah's score = 3×5= 15 points
Since Tyler scored four points less than Noah, Noah's score= 15-4= 11 points
Finally Elena's score is twice that of Tyler hence Elena's score =2×11= 22 points

HELP i’m trying to figure this out can anyone help?? the quistion is at the top of the picture.
Answer:
3/2
Step-by-step explanation:
The first step is finding two points. (4,6) and (0,0) are two easy points to use.
To find the slope, find the change of y over the change of x.
(6-0)/(4-0) = 6/4 = 3/2
